Important Notes/Cautions – from the factory
QUICK START & SETUP
SETUP 1. Install the grinder on a firm, level base in a location where it can be connected to a grounded electrical outlet of 120VAC, rated at 15 amps minimum. 2. Test the unit by running some whole bean coffee through the grinder. If any problems are encountered, refer to the troubleshooting section complete at www.wilburcurtis.com or call Technical Support at 800-995-0417.
OPERATING INSTRUCTIONS 1. Lift open the top cover of the grinder and fill with fresh whole bean coffee. Close the cover. 2. Place a new paper filter into the brewcone. 3. Insert the brewcone into the basket holder arms on the grinder. 4. Press the grind switch. The grinder will start to grind coffee. Allow the motor to come to a complete stop before removing the brewcone.
WARNING TO AVOID SCALDING, Do not remove brewcone whil brew light is flashing.
5. Transfer the filled brewcone to the brewer and press the desired brew button. The brew cycle is complete when the brew light stops flashing.
ADJUSTING THE GRINDS* 1. Empty hopper of coffee beans. Run grinder to clear grinding burrs of coffee. 2. Open housing cover to locate adjustment screw (8) and lock nut (7). Loosen lock nut. 3. Run motor during adjustment. Turning adjustment screw clockwise will result in a finer grind (if, while turning, you hear the grinding burrs starting to touch, immediately, back off 1/8th turn). Turning counter clockwise will produce a coarser grind. 4. With a screwdriver holding the adjustment screw in place, tighten the locknut. 5. Run some coffee beans through the machine to check the grind adjustment. 6. Replace front cover on machine. *This adjustment may change the amount of ground coffee dispensed.
CHANGING A BROKEN SHEAR DISK 1. Unplug the power cord. 2. Empty the hopper of beans. 3. Take out the thumb screws (10) to remove the grind cap (6). 4. Pull out the grinding burr/feed worm assembly (2). Half of the grinding burr set will remain within the housing. 5. Separate the shear cap (5) and shear drive (3). The snapped shear disk (4) should fall from the shear drive. C

6. Inspect and brush out the housing (1).. Especially look for anything that may have broken the shear disk. 7. Insert the feed worm and grinding burr onto the motor shaft. 8. Push the shear drive through the burr/feed worm assembly and align it with the tongue on the motor shaft. 9. Rotate the burr/feed worm assembly to align the slot with narrow slot on shear drive. 10.Insert a new shear disk into the slot.

TIMER SETTING – DHG
1. To set the timer, place an empty filter paper below the chute. Pour whole bean coffee into the hopper. 2. Open the lower cover to reveal the timer. 3. On the timer control board, locate the programming switch. Switch from RUN to PROG (see illustration, left). 4. On the front cover, select the desired switch to program, REGULAR or DECAF. Press and hold this switch. 5. The grinder motor and auger motor will start grinding coffee. When the desired ground coffee output is reached, release the grind switch. The auger motor will shut off, stopping the flow of coffee from the hopper. The grind motor will continue to run until the delay has elapsed. 6. Move the program switch to RUN. This will save the time setting. 7. Repeat steps 1 to 6 for the other grind switch. NOTE: Time settings in this table are only approximate. Amounts will vary with grind texture and specific coffee bean. Weigh your output, then make adjustments as necessary.
